SAP MC and saprouter string

Hello Experts,

we administer our System Landscape with SAP MC (as one of the many tools 😉 ) and currently have a problem inserting a system into it, which is in DMZ at customer side.

We are able to reach this system through our local SAPGui with saprouter string, as we have entered the systems details in saprouttab and allow connection from our PC.

For example:

Application server: sapserver.shared.dmz

Instance Number: 02

System-ID: PRD

SAPRouter-String: /H/routerhost/S/3299/H/

This works perfectly, but the question is: How can we enter this System into our SAP MC landscape?

Since we only have the option to enter Instance-Host and Insitance-Number here. Should we modify our landscape file (which are plain-text)?

We use SAP MC from our 7.31 SP05 Portal.

Thanks in advance for your help.

Best regards,

Daniel
